1. Technical Field
The present disclosure relates to positioning structures, and particularly to a positioning structure for portable electronic devices.
2. Description of Related Art
Portable electronic devices generally need to combine a plurality of components or parts such as a camera module, an earphone and so on. A typical camera module or earphone is fixed to a cover. The cover is further fixed to the main housing of the portable electronic device with screws. During assembly, the screws need to be rotated to tightly assemble the cover to the main housing. The rotating process might shift the camera module or earphone out of position, accordingly degrading the product quality.
Therefore, there is room for improvement within the art.
Many aspects of the positioning structure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the positioning structure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The positioning structure 100 is used for mounting the camera 44 and the earphone 46 to the housing 20. The positioning structure 100 includes two latching elements 22 and a positioning element 60. Referring to
The positioning element 60 is made of elastic material such as plastic or rubber. The positioning element 60 includes a cover portion 62 and two fixing portion 64. The cover portion 62 includes a top surface 68 and a bottom surface 69. The top surface 68 defines an opening 626 for exposing the earphone 44 and an aperture 628 for exposing the camera 46. The bottom surface 69 defines a first receiving cavity 622 for receiving the earphone 44 and a second receiving cavity 624 for receiving the camera 46. Each fixing portion 64 is formed at one side of the cover portion 62. Each fixing portion 64 defines a hole 642, a slot 644 and a notch 648. The slot 644 communicates with a free end of the fixing portion 64 to allow the hole 642 to increase in diameter. The combined shape of the hole 642 and the notch 648 is generally pear-shaped. Two sides of the hole 642 respectively provide an engaging guiding surface 6422.
It is to be understood, however, that even through numerous characteristics and advantages of exemplary embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
